I've made a custom gamemode based off of TF2's existing mode, Control Points.
I've also edited de_dust2 to be compatible with the gamemode.
There are 3 control points, which you have to capture.
The middle one is unowned, and the other two are owned by each team.
The middle starts unlocked, the other two are locked.
You must try and capture the middle point, by standing inside it.
If anyone of the opposite team is on the point, the capture percentage freezes.
The more players you have on the point, the faster the capture will be.
Once you have captured the point, the point belonging to the other team is unlocked.
If the other team manages to recapture the middle point, their control point is locked, and the other team's point is unlocked. This can continue until a team captures all three points.
Go play!
